I had the same issue. The "'g_APinDescription' was not declared in this scope" error happens when the wrong board is selected in the Arduino IDE. In my version 2:1, I couldn't select the correct "Arduino Due (programming port)" for some reason. Instead I downloaded version 1.8 and was able to install and update the board through Tools > Boards > Board manager. After restarting the IDE and compiling, the code works perfectly. I have no idea why the correct "Arduino Due" doesn't appear in the version 2 of the IDE, but this fixed the issue anyhow.
